CTICasesPulmonary Adenocarcinoma with Retained Acupuncture Needles

Imaging findings
Multiple retained acupuncture needles in the subcutaneous tissues of the back. Chest CT shows right lower lobe consolidation initially resembling lobar pneumonia, persisting and worsening over months, with small nodules elsewhere, cavitation/pseudo-cavitation, and presumed desendothelial bronchiolar/aerogenous spread to both lungs.
Key takeaways
Persistent consolidation despite antibiotic treatment, especially with associated nodules and cavitation, should raise suspicion for adenocarcinoma rather than atypical infection. The patient's demographics (Asian woman, nonsmoker) are relevant for EGFR mutation screening in adenocarcinoma, which can show aggressive progression despite targeted therapy. Retained acupuncture needles are an incidental finding.
